Serial No. 418,137. v I

My invention relates to new andy useful im rovements in swifts for reeling machines, anc more particularly to a mechanism for either quickly locking the swift in its reeling the swift to collapse, so that the skeins may be quickly removed. I

Still another object of the invention is to provide a locking mechanism for the swift,

- whereinall of the Vworking parts of the lockmal position.

ing ymechanism of the'swift` are enclosed, so that there willbe no parts projecting to interfere with the operator or to Vcatch any of the yarn when removing the skeins.

Still another objectl of the invention is to provide a swift wherein there are two sets of brackets, each set being controlled (locked or collapsed) by the inward or outwardy movement of a central shaft or spindle, the respective sets of'brackets being so connected to the spindles that the movement of a spins dle in one direction will collapse its brackets or a movement of the spindle in the opposite direction -will lock the brackets in their nor- With these and other objects'in view,the invention consists incertain new and novel arrangementsv and combinationof parts, as will be hereinafter more fully describeduand pointed outV in theV claims.

Referringnow to the drawings showing a preferred embodiment, i e l Fig: 1 is a side elevation of a reeling swift, the brackets to theV left being shown in their working. or normal Vpositionand the brackets tothe right in the full lines being shown in their collapsed position, and the olotted lines showing the bracketsin theirnormal or lockedl position; t y

Fig. 2 is an enlarged sectional view throiigh one of the two oppositely located main spindies and showing the locking ,mechanism atv the end of the spindle in its normal position;

Fig. 3 is a view similar to Fig. 2 loutfshow-y ing the locking mechanism after loeingun-V locked, y, the dotted lines showing the links of the spider and brackets as being moved to their collapsed position;

, Fig. 4: is an end view of the locking knob.`

At the outset,it might be mentioned that the gist of the invention istheV mannerv of connecting the brackets to a collapsible spider, the means for locking the` spider in its normal position, and the manner invwhich the parts are formed and operated.`

Referring now to F ig. 1, thereisshowna portion of a frame 1, which may loepartv of a reeling machine, to which is vsecured a base or standard 2, in which theremay be mounted'fa cross shaft 3 which will, in' turn,be driven 5, may operate 4the geary andv other lparts which may operate or revolve the entire reel@ ing swift. This central part or head s o far described may b e of any desired type. and

the various parts, such as clutches, releases andV brakes, arenot described, as they form no part of the present invention. 1

Still referring to Fig. 1, and glancing to the left half of the machine, there may lbe seen a spindle or shaft 7 over which there lits a partly hollow shaft 8, on thevrearend of which isformed a non-collapsiblespider 9 to which, in turn, is pivotedthe arm 10 of abrarcket 11, and likewise there may be vseen a similarlower bracket 12 with itsinner end or arm 18 pivoted, as atlfl. It will be understood that there areV generallyxabout six of these bracketsconnected to each of the shafts. It might Vbe mentioned here thatthe 70 by a pulleye, which shaft, throngh a worm same arrangement is carri'edout to the right of the swift and the parts are identical, so that a descriptionV of the VY'one halt of the `mas chine, therefore, will be a description of the lapsing and locking means for holding these brackets in their collapsed or normal? position will be set forthar, I v l Referring'n'ow'more particularly to Figs. 2 and 3, the hollow shaftLS: andthef spider' 9 are secured bythe bolts l5 to the revolving hea-d. This spider '92 is @if'ormedv `withfa plurality Aof biturcated` lugs 1G around its periphery which, in turn, respectively encasethe heretofore mentioned lower arms 10A Vof the` onefbrael'et and' the' inner arm 13 of the opposite bracket.' ln the i i same manner, all theA rearilower arms of the various brackets will be' pivotally supported, as will be clearly understood. l Y

InA the hollow shaft 3*, there mayl beY seen i theV bearing or'supportingshatt and it will ou-t portion 1'8, as'ma'y befre'adily seen.

bel understood that the' rotation of the shaft 8A and its integral spider will, of course, revolve the brackets connected therewith.

This shaft 8 nearit's outer' end isz slightly reduced", as at 17, and from a peint near'this reduced portion, itjisYcut-'out'fas atlytor the reception ota formv oflockings 19 which is held inposition by the pin 201 "its may also be4 seen in' Fig; 2', the cut-outporL tion 18dips' still'urthfer, as at 2l,.to'provid"e for the full downward movement of the4 outer end-ofthe spring. This springlQ is rounded on its lower vsurface at its` inner" end', as at 22, and snugly rests andllits within the cutf The shaft '8, in turn, at its outer en'di-s provided with another main sleeve 23,'which slidingly fits over theendlof the-shatt- 3 and covers thei cut-out portion 18' and the' lock spring therein. 'TheL sleeve 23" is externallyV threaded, as at 24, and a small bea-ring collar AZ5-is threaded over the same; Theinner end ot the sleeve 23- has a plurality of peri-phj-V erally spaced lugs 26 thereon, vto'y which will be pivoted respectively links 27 which, in turn,rrec`eives a lug 28 formedon the lower surface of' each bracket whilea pivot'2`9`` is passed through each link andthe lug, sozthat the brackets may bev collapsed, asV will shorthv ly'be described?.

' These various toggle linksv connected-4to" the respective brackets and connected to the-lugs movedoutwardflyand' collapsed, the' brackets,

will als@ bel collapsed, or their' outer'l ends tilted inwardly, so that the skeins may be quickly removed from the same.

' Referring again tothe end of the sleeve 23,

there will beV seen slidingly litted on the collar Vthe cored knob 30, which knob is recessed, as at 3l, so as to justrnicely i'it on the aforementioned collar 25.

The knob is reduced on its outer periphery, as ,at 32, and externally threaded, while threaded thereon is a small collar or cap 33 that has the rinr 34 slidingl'y engageable with theouter` surfaceof thevv sleeve 23, so that when the knob ismoved to the lefthand,

the rim 34 contactswith; atace et the collar 25. ;Reterring 'n o-w for the moment again to the springrli9, it will be seen that there is a 'trig'geri formation 4at its rear end, that is,

there isa small seat 35 and an upstanding l'u-gf 36 normally lits against the outer surface 2.5a of the collar 25. When this lug 3b ofthe spring is' up' behind the 'collar 25, the sleeve 23 cannot move tothe lett or laterallyenits shaft 8,. because the spring, it

' will' berememberechis locked by the pin 20 to' the main shaft 8 and, therefore, the shaft, link, andbra'ckets connected therewith' cannot collapse, but twilll be held-in theirlo'cked or normal position, asV maybe seen4 trom the left stragi." Y i f Re'ierring'again to the' locking knobj 30, it will; be' seen 'that `the outer end is' provided witli'aA tapered bere 37, wlril'ethe end otthe spring I9* has the: projecting finger' 38 with a' slight taperV formedv thereon', so that when this-knob. is pulled outwardly, theitapered bore ot the knebv will force the spring finger downwardly to the position shownil-in'Filg. v3 and thuslower thelug 36 from' infront 'of the inved torth'e'position shown in Fig; 3, the rear'collar'or cap 33 or ratherits rim 34 will now enga-ge the reanface ofthe' collarj25, vso that the knob now oni afurthermovement to the left'willp'ull kthe sleeve; 23 outwardlyto thus collapsethe various links 27, or, inother .words', collapse the spider'or break the link,

and thusy cause' the brackets to' tilt4 inwardly at their outer ends',.nraking itnow possible *the lug 36 Yin agtl; SHPl Up in front ofthev tace 25a of thecollar while the continued inward pressure on t'he' knob will then'torce the sleeve 23`inwardlly oniits shaft Sand again force the links-27 in tn-upright vposition to thus straighten the brackets and' then lock reageer these links of the spider in their normal position. Y

The swift may again be operated and as long as the little knob is not pulled outwardly, the toggle and the brackets will remain in their normal and locked position.

It will be understood that although l have described one set of brackets and its locking mechanism, the parts will all .be duplicated and there will be the two main shafts and their locking means, so that the brackets on either half of the machine may be readily collapsed or locked, as desired.

From the foregoing, it will be seen that l have provided a locking mechanism for a swift wherein the several brackets maybe readily collapsed by simply grasping a little locking knob and giving it a preliminary pull and then a continued pull which, in turn, will collapse the spiderv or break the toggle and allow the brackets to collapse, while to set the brackets again in the normal position it is simply necessary to force the knob inwardly until its sleevefhas returned to its innermost position, where the links will again be locked and will remain locked until the trigger mechanism is again released by an out ward movement ofthe knob. Y c Y y It will furthermore be seen that all of the locking mechanism is fully enclosed, so that there are no projections toV interfere with the operator or to snag or catch any of the yarn when the skeins are being removed.

Many slight changes might be made without in any way departing from the spirit and scope of the invention. Y Having thus described my invent-ion, what I claim as new and desireto secure by Letters Patent is y l. In a collapsible swift, a central shaft, brackets pivoted at the rear ends to said shaft, a sliding sleeve on said shaft and link mechanism radially connected to said brackets, a knobon said sleeve and a trigger on said shaft extending into said knob, said trigger normally positively locking the sleeve to prevent lateral movement of the sleeve and said knob cooperating with lthe trigger so that when said kno-b is initially operated the trigger will be released and the sleeve capable of sliding movement to thereby tilt said brackets.

2. A collapsible swift comprising a plu rality of brackets, a central shaft, the said brackets pivoted at their rear to said shaft,

a slidable sleeve on the endY of said shaft provid-ed with radial links extendingthere- Y from and said links normallysupporting the brackets in their operativeV position, a knob on said sleeve and alocking finger on said shaft cooperating with said knob to thereby prevent the collapse of the brackets, said knob capable of being moved outwardly on said sleeve to thereby operate. the locking finger and toi-permit the sleeve to -be also laterallymovedv` tof'thereby collapse the brackets.

engaged from the sleeve, the latch finger f normally fittingV in front of the said collar whereby an outward movement of said knob will force the latch finger out of its locked n position to thereby permit the sleeve to be pulled outwardly. l

4. In a reeling swift, a shaft,` a slidable sleeve on said shaft,the end of the shaft pro-V vided with a recess and a latchfinger fastened within said recess, the said latch finger having a tapered end extending beyond the end of .the shaft and a. collar threaded on the end of the. sleeve and slidable on saidvcollar, a

cap on the rear of said knob and adapted to l engage with said collar when the knob is pulled forwardly, said knob provided with a tapered `bore at its end and the walls of the bore engaging the end of the latch finger, the latch finger having arseat normally engaging the collar on the sleeve 'whereby the sleeve is normally locked against movement on the shaft Awhereby a preliminary outward movement of the knob willv release the latch finger from the collar and permit the slidable sleeve to be actuated.

5; A locking mechanism Vcomprising Va shaft and a movable sleeve on the end thereof, the end of the shaft having a recess and a latchv finger fastened therein, the end of the finger ext-ending beyond the end of the shaft, a collaron said sleeve and the latch finger normallyengaging the collar to there-` by prevent lateral movement of the sleeve, a knob on the sleeve and slidably engageable with the collarthe end of the knobhaving a tapered bore cooperating withthe end of thevspring finger whereby a preliminary outward movement of said knob will release said sleeve against movement, a knob on the sleeve and cooperating with. said latch whereby `a preliminary outward movement of the knob will release the latch and permit the sleev to be movedv outwardly. k7. A locking mechanism to normally prevent the movement of a sleeve on a shaft iso comprising, a shaft'havng recessvformed v l in its end, a latch ngenfltting Within said recess, asleevev over said recess and-linger i Y and the end of the nger'normally holding the sleeve from lateral movement, 'a knob slidably mounted on the sleeve, the knoband the envdvof the latch nger so formed theta preliminary movement of the knob will release the latch linger and permit the sleeve `to i. be drawnontvvardly.
